not flow backwardly into the steam supply pipe. v

In the drawing 'Figure 1 shows in vertical section, a device constructed in accordance with the invention, parts appearing in elevation, and a portion of a radiator being shown Figure 2 is a section on the line 2 2 .of Figure 1, distant parts being omitted; Figure 3 is an end view of the connection and attendant parts, the same being detached from they radiator; Figure 4 is an elevation of the valve cage.

Referring in detail to the drawing, wherein like characters ot reference designate like parts in all of the views, a portion of a radiator is shown generally at 5 and the numeral 6 designates the steam supply pipe.

The device includes a casing 10 which is provided with a lateral nipple 11, and with a nipple 12 which receives the pipe 6. lThe casing 10 is provided with a valve-seat 13 upon which a slidable valve 14 cooperates..

The valve 14 has an interiorly threaded neck 15 in which a stem 16 isthreaded. The stem 16 is rotated by a handle 17. v A screw plug is mounted in the valve 14 and gives access to the threaded bore of the neck 15.

Encircling the valve 14 is a cage 18 having slots 51 which permit the passage of steam. The numeral 19 marks a tubular connection, the outer end of which is unitedl by a union 20 with the nipple 11. The tubular connection 19 is provided with a retarder 22, extended into the radiator 5, a troughshaped conduit 23 for the water of condensation being carried by the retarder and by the connection 19. The conduit 23 comprises a shell 21 partially enclosing the connection 19 transversely, the shell being joined to the connection by an outer end wall 53 and by an inner end wall 54. The conduit 23 includes a vnarrowed extension joined to the retarder 22 and opening through the inner end wall 54. The extension 55 is joinedv at.

its upper end to the retarder 22, as shown at :P TENT; FFEBC r ann-Intron VALVE.

by conduction directly-from the retarder '22.

A nipple 26 extendsv downwardly `from the: shell 21 and is 'cnnected to' a pipe 27 the` nippleand the pipe constituting an outlet.

56, wherebythe conduit23'will be heated.`

The lower portiono'ff-the extension 55 is i provided with an inlet" 28, for the rwater of condensation. 'A nipple 24;.proje'cts@from` the extension 1 55.l 'The' extension" 55,'v which `forms part oiiyrt-he:` conduit "23vis [supplied with an V"airy inletV 25,vlocated?y within. the

nipple 24. The nipple 24 is connected with.y a pipe 52 which is ,extended within the ra# diatoi' to the farend of the radiator and is adapted to conduct air. therefrom and dischargethe saine into ther conduit`j23 and thence through the .pipe 27. The steam,

beingl lighter than air, rises in the radiator y.

A valve 29-extendsl diagonally across the while the air passes out as above stated.

member 19 and iszthreaded thereto, the valve being slidable in an openingl 30 in4 theretarder 22 and being adapted. to control the inlet 28 for the water of condensationLthe outer end of the valve 29 having a screw driver kerl 29a.

From the disclosureit will be apparent,

`that water rising 'in the "lowerend 'of a radiatorv willbe prevented from lowing'back to the pipe 6'owing to thepresence ofthe retarder 22. The -water will How through the inlet 28 and be discharged by way ofthe conduit. 23 and the pipe 27.v 1t will alsobe so l be discharged through the Vpipe obviousthat air conducted through'the conduit 23 will 27.

What is claimed is`:-- y i v 1. In a device of the class described, a tubular connection provided with a retarder and a trough-shaped-conduit for the water I of' condensation, the conduit being carried by the retarder and the connection being joined at its upper end. to the` `retarder,

whereby the conduit willbeheatedbycon-` duction directly trom the retarder, the coni duit having an outlet, and being provided in its lower portion with yan inlet lior the water of condensatiomthe 'conduit having any air `inlet located between the inlet for the water of condensation and the point of juncture between the upper .end of the conduit and the retarder; and a valve controlling the y passage of steam through theA connection.

2. In` a device ofthe'class described, a.

tubular connectionprovided witha retarder, and a trough-'shaped conduitforthe water of condensation, the yconduit being carried by the retarder and the connection being 3. In a valve for radiators, a casing f adapted to be connected With the steam supply ypipe and includinga laterally extending nipple, a union connected with the laterally extending nipple and with a tubular connection for engagement with the intake port of a radiator, a Wall formed at the bottoin of the connection extending longitudinally thereof andprojecting'out of the saine,

that part oi the Wall which projects out of the casing being curved upwardly,` a conduit formed upon the outer face of the Wall having an opening therein adapted topermit the passage of air therethrough,`a nipple formed upon the opposite end of the con# duit, said end being also provided with an opening for the passage -of Water therethrough and a valve in the union adapted to control the Water opening,

VIn testimony that I claim the foregoing as iny own, I have hereto ailixed my signature in the presence of two Witnesses.-
